The MC4558 is a high performance monolithic dual operational amplifier produced by ST company. It has internal compensation, short-circuit protection, gain and phase matching, low power consumption, and pin-to-pin compatibility with MC1458/LM358.
The MC4558 is a high‑performance dual operational amplifier that combines the features of the MC1458 with three times the unity‑gain bandwidth of the industry standard. It offers internally compensated operation, short‑circuit protection, low power consumption, and pin‑to‑pin compatibility with MC1458/LM358.
The document provides absolute maximum ratings, electrical characteristics such as gain‑bandwidth product, slew rate, and input offset voltage, as well as mechanical data for DIP‑8, SO‑8, and TSSOP‑8 packages. Order codes, typical application schematics, and revision history are also included.
